Answer
Explain the process that caused the swelling in her knee and the benefit of that process.
The swelling is due to accumulation of synovial fluid, as she soaked the knee in hot water bath tub, the heat has increased blood flow to the knee and resulted in the swelling. As we know the heat will help you relieve of your pain, to relax and help you to regain the knee flexibility
Which arteries are involved in carrying blood to this site?
Popliteal artery, which is a branch of the femoral artery, supply blood to the knee, thigh, and calf and this artery finally ends at the anterior and posterior tibial arteries.
What changes do you expect in those arteries?
Due to the twist, these arteries might have injured.
Did her time in the hot tub affect the swelling? If so, what affect did it have and how did it cause this effect?
Yes, obviously the time she spent in the hot tub would have affected the swelling. The heat in the water would have increased blood flow to the injured area, resulting in the accumulation of synovial fluid around it.
What should Martha do now?
It is better to apply ice pack on the swollen knee so that she can reduce inflammation and when the swelling will reduce, she can apply mild hot pack to get relief from pain, till pain will completely reduce, she needs to take complete rest and try to keep the knee at elevated level to avoid swelling.
